Mapping the Great Barrier Reef: the Catlin Seaview Survey

For Ove Hoegh-Guldberg, the project’s chief scientist who began snorkelling on
the reef as a 10-year-old in 1969, the survey offers the first chance to
observe life at such a depth. "Over 90 per cent [of the Great Barrier Reef]
was pretty much unexplored, which is an amazing fact," he said. "Now with
these deep diving robots and some of the technology we are developing, the
potential is there for unlocking those secrets."
